LUBRICATOR.

Specification of Letters Patent.

Patented Apr. 9, 1912.

Application filed September 13, 1911. Serial No. 649,008.

To all whom it may concern Be it known that we, LEOPOLD KAssANDER andOTTO Bnsr, citizens of the United States, and residing in the city,county, and State of New York, have invented certain new and usefulImprovements in Lubricators, of which the following is a specification.

Our improvements relate to multiple feed lubricators used in connectionwith locomotives, and in which the oil passes from a suitable reservoirin visible drops through a body of water into the tallow pipes andthence to the parts to be lubricated; and we have represented them inthe drawings, to be hereinafter more particularly referred to, asapplied to that type of this class of lubricators in which the sightchambers and oil passages leading thereto are contained in a structurecast integral with, but located below and outside of the oil reservoir,as illustrated in U. S. Patent No. 844,281 of F ebruary 12, 1907,wherein is shown a triple sight-feed, condensation-displacement,balanced-pressure lubricator of this kindeach sight feed as usual havingits own regulating valve, and two of the feeds leading to the enginecylinders and one of them leading to the air pump, as customary intriple feed lubricators.

The object of our invention is a suitable, effective and economicalcut-out, whereby communication between the oil reservoir and all of theoil passages contained in the said structure, cast integral with butlocated below and outside of the oil reservoir, may be controlled by asingle valve arrangement, the same being preferably so constructed andapplied that one or all of the oil passages can be opened or shut asdesired. This valve arrangement, whereby all of said oil passages arecontrolled, is located in the casting outside of and below the oilreservoir, and between the sight-feed regulating valves hereinbeforereferred to and the reservoir, and is in addition to, and independentof, said regulating valves, which are retained in order that each sightfeed may be regulated independently of the others.

We are aware that it is not new in multiple feed lubricators to providea valve foreach feed to regulate the amount or rate of oil dischargefrom that feed independently of the others, in combination with a singlecut-out valve, between said regulating valves and the oil reservoir, foropening and closing communication between said feeds and the oilreservoir. We are also aware that it is not new in multiple feedattachments, to provide a single valve, in the nature of a three-waycock, whereby one or all of the feeds can be cut out or turned on. Weclaim neither one of these features, broadly considered.

Our invention resides in the structural details and relative locationand combina tion of parts which form the subject of our invention, andwhich we will now proceed to describe by reference to, and in connectionwith, the accompanying drawings forming part of this specification,

In said drawings-Figure l is a longitudinal section on line 11, Fig. 4,with the cylinder feed attachment partly in elevation. Fig. 2 is a crosssection on line 2-2, Fig. 4. Fig. 3 is a cross section on line 3-3,Fig. 1. Fig. 4 is a top view of a lubricator embodying our invention.Fig. 5 is a front elevation of that portion of the elevator wherein thecut-out valve arrangement is located Like letters of reference indicatelike parts in all the figures.

A is the cylindrical oil reservoir placed horizontally and provided.with threaded necks B for connecting the oil pipes which lead to theparts to be lubricated. In this instance there are three such necksleading, the two end ones to the engine cylinders, and the intermediateone to the air pump.

C is the condenser with the usual valve and steam supply connections D.

E are the equalizing pipes and F the equalizing steam passages whichlead steam behind the choke-plugs G; H, filler plug; I, valvecontrolling the passage of water from condenser to bottom of oilreservoir through tube K; L L, gage glasses (one of them shown insection in Fig. 4,) to indicate contents of oil reservoir, and frontingthe same way as the sight feed glasses; M, oil tube; N, drain valve; 0,blow out valves for sight feed chambers; P, feed regulating valves; S,sight chambers communicating with outlets B, through channels T cast inreservoir; U, feed nozzles in lower part of sight chambers; X, screwcasings in front and back of sight chambers and containing the disksight feed glasses. From oil tube M lead the passages through which oilis conducted to the sight chambers. The oil passages and sight chambersare contained in a structure which is cast integral 1 with and locatedbelow and outside of the oil reservoir.

Thus far there is nothing essentially new in the lubricator or differentfrom the lubricator of Patent No. 84t,281, and the reference lettershereinbefore used indicate the same parts in the patent as here, thesame being a triple-feed, condensationdisplacement, balancedpressure,locomotive lubricator of known type. Upon a lubricator of this kind isengrafted the cutout arrangement which forms the first part of ourimprovements, and which we will now proceed to describe.

The casting which contains the sight feed chambers and oil passages thusfar referred to, and which is integral with and located below andoutside of the oil reservoir, we designate by the reference letter Z. Inthe casting Z, at some suitable pointin this instance at a point betweenthe air pump sight chamber and the left hand cylinder sight chamberisformed a chamber Y, which may be conveniently of cylindrical form, itsaxis being horizontal and crosswise of the length of the casting. Thefront wall of the chamber is formed by a screw plug Y, which closes themouth of the chamber, and which carries the movable portion of thecut-out arrangement. The oil tube M communicates with the chamber Ythrough a vertical channel WV, in casting Z, fitted with a plug w, intowhich the oil tube is screwed as indicated in Figs. 1 and 8.

In a thickened portion of the casting, back of the chamber Y, are formedtwo horizontal oil channels V, V, which extend lengthwise of thecasting, and are arranged the one vertically over and parallel with theother. The upper passage V is the longer passage, extending virtuallythe length of the casting. It is closed at its ends; communicates withthe chamber Y through a hole or port a, formed in the rear wall of saidchamber; and near each end it has a port o through which it communicateswith the steam cylinder sight chamber S at that end, opening into thespace in said chamber below the feed nozzle U therein. The lower oilpassage V is shorter, extending only from the chamber Y to theintermediate or central air pump sight chamber. It communicates withchamber Y through a hole or port o in the rear wall of the same, andwith the space in the central sight chamber below the feed nozzletherein through a port 12 Thus the vertical and horizontal oil channels,while contained in the casting Z, communicate, not directly with oneanother as in Patent No. 8%,281, but through the intermediary of thechamber Y. This chamber, however, is also contained in the casting, andby locating it therein at the level of the lower and narrower portionsof the sight chambers, we find ample space between adjoining sightchambers to accommodate the chamber Y without any increase in the lengthof the casting, over that which it has in the existing form oflubricator. By 10- cating it at that level, the horizontal oil channelsV, V are also brought to the same level where they can open convenientlyand directly both into the chamber Y and into the spaces in the sightchambers below the feed nozzles U. Nor is the casting thicker from frontto rear, save for the slight increase in thickness along the line wherethe horizontal oil channels V, V are located.

The plug Y which closes the front of chamber Y is annular, havingthrough it an axial cylindrical hole for the passage of the cylindricaloperating stem R of the cut-out arrangement, and a stuffing box Y forpacking said stem. Suitably secured on the squared outer end of the stemR is an operating handle Q. On the inner end of the stem is a shoulderedhead R, contained in chamber Y. The shoulder bears against the innerface of the plug Y which forms the front wall of the chamber. In thatface of an offset portion of the shouldered head which confronts therear wall of chamber Y, are formed two cylindrical horizontal sockets toreceive the cylindrical stems of two disk valves 1", r, one of whichfits in each socket and is pressed outwardly by a spring 8, which holdsthe head of the disk valve with yielding pressure closely against therear face of the chamber Y, which is dressed off for this purpose, so asto permit the valve disks to move smoothly over the face of the rearwall when the operating stem R is revolved. The two disk valves 1, 1"are so located that when the cutout is closed, valve r will cover lowerport '0 and valve 1" will cover upper port 1) and the parts are sospaced and proportioned that when the operating handle is turned to movethe valve from right. to left, the valve 9 in its travel-and when aboutmidway between open and shut p.ositions-will, as seen in Fig. 1, closethe upper port 4) which communicates with the upper horizontal oilchannel V through which the sight chambers of the cylindrical sightfeeds are supplied with oil, but leave open the lower port 4) whichcommunicates with the lower oil channel through which the air pump sightfeed is supplied. The cut-out is in fact a threeposition cut-out, asillustrated by the words Open, Air pump and Shut on the indicator plateshown in Fig. 5. A spring detent device 00 of any suitable constructionis employed to hold the handle in either one of the three positions.lVhen the handle is at Open (in which position it is shown in Fig. 5)both ports o, 1) will be open; when it is at Air pump, the air pump port'1) will be open, while the cylinder port 1) will be shut, as indicatedin Fig. 1; when it is at Shut, both ports 4), 2: will be closed. Un-

der this arrangement it will be noticed that a single cut-out valvecloses and opens communication between all the sight feeds and the oilreservoir, thus permitting the feed regulating valves P to be used onlyfor the purpose of feed regulation and to remain undisturbed in anyposition of adjustment.

The threeposition cut-out is of advantage, inasmuch as it permits theair pump supply to be opened up without opening up the steam cylindersupply alsowhich is frequently desirableas for example when the engineis at rest. If desired we may employ a single long horizontal channelwith a port or opening communicating with each one of the three sightfeeds, such as the channel V illustrated in U. S. Patent #844,281, towhich the cut-out valve may be applied in an obvious manner. Thethree-position cut-out, however, is preferred for the reasons abovesuggested. Furthermore the heads of the valves 1", 7" may be connected,so as to constitute a single flat continuous spring pressed valve plateof dimensions to cover the two ports 4;, 0 when in Shut position. Thearrangement illustrated is, however, preerred.

It is desirable that the lubricator should be provided also with a feedfor the air cylinder of the air pump of the locomotive, which shall beindependent of the usual steam cylinder and air pump feeds, and whichmay or may not be used in connection with the lubricator as desired.Such an air cylinder attachment is represented at the right hand end ofthe lubricator in Fig. 1, comprising, as there shown, a body f having abonnet 'n, at top, and at bottom a part we containing a sight feedchamber closed by glass disks p and nuts q, for sight purposes. Acoupling (Z connects the attachment to a pocket a in the side of thelubricator in the top of which is screwed a tube 7;, the upper end ofwhich opens into the oil chamber of the lubricatorthe tube beinginserted in place through an opening in the top of the lubricator closedby a plug 0. Parts (4, b, 0, are present on both sides of the lubricatorin Fig. 1, so that the aircylinder feed attachment can be applied toeither side as preferred, the pocket on the unused side being closed bya screw plug 6 as shown on the left of Fig. 1. We do not, however,describe in detail the construction and arrangement of this attachmentand its related parts in the lubricator, inasmuch as the same is madethe subject of a separate divisional application for patent in our namesSerial No. 659,230, filed Nov. 8, 1911.

Having described our improvements and the best way now known to us ofcarrying the same into practical effect, what We claim herein as new anddesire to secure by Letters Patent is as follows:

1. In a multiple sight-feed lubricator, the combination with the oilreservoir and steam-equalizing and 0il-pipe connections of a castingintegral with, and below and outside of, the oil chamber, sight chambersand vertical and horizontal oil-supply channels therefor contained insaid casting, regulating valves, one for each sight-feed chamber, avalve chamber also formed in said casting at the junction of thevertical and horizontal channels therein and located in that portion ofthe casting in front of the horizontal channels and in the intervalbetween two adjoining sight-feeds, a rotary disk cut-out valve forcontrolling ports in the vertical rear wall of said valve chamberleading to the horizontal oil chambers, and an operating stem and handletherefor extending through to the front of the casting and supported inbearings therein, the acting face portion of said cut-out valve whichcontrols said ports being movable to and from the rear wall of the valvechamber, and spring-pressed toward and against the same, substantiallyas and for the purposes hereinbefore set forth.

2. In a multiple sight feed lubricator the combination with the oilreservoir and steam-equalizing and oil-pipe connections, of a castingintegral with and located below and outside of the oil chamber: air pumpand steam cylinder sight-feed chambers contained in said casting, andregulating valves, one for each chamber; a cut-outvalve chamber formedin said casting, and a vertical oil channel leading thereto from the oilpipe; two horizontal oil channels '0 '2) located in the casting back ofthe cut-out valve chamber and one above the other, the one communicatingwith the two steam cylinder sight-feeds, the other with the air pumpsight-feed, and each having its own port opening into the cut-out valvechamber; a rotary disk cut-out valve controlling said ports and arrangedto open at will either both the steam cylinder and air pump ports, orthe air pump port only; and an operating stem and handle for saidcut-out valve, extending through to the front of the casting andsupported in bearings therein, substantially as and for the purposeshereinbefore set fort-h.
